I use an LG C1 as my primary display now. After Rtings video and data on burn in there's no need for FUD.

Even if I were to use my display for 6 hours a day for 3 years only watching CNN, which is a crazy test, the burn in is minimal. Rtings results. And the LG C2 basically has none, which shows how much better tech has gotten.

Unlike CRTs, OLEDs don't burn in. They burn out. So you can even out the wear and mitigate it. As long as you run compensation cycles for TFT layer retention it's fine. You can notice the whole screen shifts a pixel at times, but it's not often (once every hour?). I use an all-black screensaver that kicks in after 5 minutes.

I wouldn't trust Samsung's code though. They don't run maintenance cycles sometimes. Maybe you can fix it by being on top of when Samsung fails to do it manually, but it's good knowing this LG will probably last me yet another couple of years. And by then, I'll probably want a better TV/monitor anyway.

Phones don't have all these features IIRC. TVs are built for longer use. Maybe that's intentional.
